On this page we list the current priorities for GEOS-Chem development. This list was compiled by the user Working Groups at the last International GEOS-Chem Meeting (IGC8) in May 2017 and was updated in May 2018 following the release of v11-02 which included a number of these priorities. This list will be continuously updated based on code readiness and input from the Working Groups and the Steering Committee.
We also invite you to view our GEOS-Chem Support Team project management board on Trello.com, which shows the current GCST workflow.

12.0.0
VERSION CURRENTLY IN DEVELOPMENT
GEOS-Chem v11-02-final will also carry the designation GEOS-Chem 12.0.0. We are migrating to a purely numeric versioning system in order to adhere more closely to software development best practices. For a complete description of the new versioning system, please see our GEOS-Chem version numbering system wiki page.
The following updates and fixes are slated to be added to GEOS-Chem 12.0.0 (aka v11-02-final). Many of these updates fix issues that were identified during the GEOS-Chem v11-02 release candidate testing period.
Please see the following link for complete information about the validation of GEOS-Chem 12.0.0:
- Approval form for 1-month benchmark simulation 12.0.0
- Results for 1-year benchmark simulation 12.0.0-Run0
